I moved your thread description to the first post and trimmed it above, OP, since it was taking up a lot of space on the forum listing. Try to keep thread descriptions under 7 lines so you don't visually crowd out other people's threads. ~Zyn

No outside source of materials has yet been determined for these structures.

What do you mean here? The origin of the structures? Or the material composition of them?

Okay, so we have a prosthetic device that can replicate to be any organ but does it only to replicate itself in the end. That is just scratching the surface of the SCP.

Consider some of these for food for thought. Why would it go through such means to replicate itself? Why masquerade as prosthetics? How is it aware of which organ it needs to replicate? Was it meant to be a prosthetic or meant to self-replicate?
